Predicting drinking outcomes: Evidence from the United Kingdom Alcohol Treatment Trial (UKATT).

AIMS: To explore client characteristics that predict drinking outcomes using data from the UK Alcohol Treatment Trial (UKATT). METHODS: Multiple linear regression was used to determine if there were any characteristics, measured before the start of treatment, that could predict drinking outcomes at three and 12months, as measured by percent day abstinent (PDA) and drinks per drinking day (DDD) over the preceding 90days. RESULTS: Lower baseline DDD score and greater confidence to resist drinking predicted lower DDD at both three and twelve months following entry to treatment. In addition to baseline PDA and having greater confidence to resist heavy drinking, female gender, aiming for abstinence, more satisfaction with family life and a social network that included less support for drinking were predictors of percent days abstinent. CONCLUSIONS: Overall the strongest and most consistent predictors of outcome were confidence to avoid heavy drinking and social support for drinking. More predictors were identified for percent of days abstinent than for drinks per drinking day. For percent of days abstinent, a number of client characteristics at baseline consistently predicted outcome at both month three and month twelve.

Exploring treatment attendance and its relationship to outcome in a randomized controlled trial of treatment for alcohol problems: secondary analysis of the UK Alcohol Treatment Trial (UKATT).

AIMS: To identify client characteristics that predict attendance at treatment sessions and to investigate the effect of attendance on outcomes using data from the UK Alcohol Treatment Trial. METHODS: Logistic regression was used to determine whether there were characteristics that could predict attendance and then continuation in treatment. Linear regression was used to explore the effects of treatment attendance on outcomes. RESULTS: There were significant positive relationships between treatment attendance and outcomes at Month 3. At Month 12, these relationships were only significant for dependence and alcohol problems for those randomized to motivational enhancement therapy (MET). There were significant differences between groups in attendance, with MET clients more likely to attend than clients allocated to social behaviour and network therapy (SBNT). MET clients were also more likely to attend all sessions (three sessions) compared with SBNT (eight sessions). MET clients with larger social networks and those with confidence in their ability not to drink excessively were more likely to attend. SBNT clients with greater motivation to change and those with more negative short-term alcohol outcome expectancies were more likely to attend. No significant predictors were found for retention in treatment for MET. For those receiving SBNT, fewer alcohol problems were associated with continuation in treatment. CONCLUSION: Attending more sessions was associated with better outcomes. An interpretation of these findings is that, to improve outcomes, methods should be developed and used to increase attendance rates. Different characteristics were identified that predicted attendance and continuation in treatment for MET and SBNT.

Dilated and echogenic fetal bowel and postnatal outcomes: a surgical perspective. Case series and literature review.

INTRODUCTION: Foetal dilated or echogenic bowel have been described as markers for a variety of conditions including bowel obstruction, chromosomal and infectious disorders and cystic fibrosis. We aim to describe possible surgical interventions and outcomes. METHODS: A 5-year review was performed of the clinical course of infants with antenatally diagnosed isolated echogenic bowel and/or dilated bowel or intraabdominal echogenic foci presenting at Princess Margaret Hospital for Children, Perth, Western Australia. RESULTS: Abnormal antenatal findings were present in 35 foetuses. Twelve babies underwent surgery for intestinal atresia, meconium ileus and duplication cysts. Postoperative courses and outcomes were good. CONCLUSIONS: Echogenic bowel on antenatal ultrasound is a non-specific marker for a variety of disorders. Although associated with higher rates of foetal loss, the majority of neonates are normal at delivery. Bowel dilatation with or without echogenicity is often predictive of bowel obstruction requiring surgery. Surgical outcomes are, however, very good. Echogenic foci elsewhere in the abdomen have little postnatal significance.

Incorporation of Integra in tissue defects: a pilot study in the rat model.

Integra has been shown to be very useful in accelerating the growth of neodermis. It has found extensive use in case of burns as a primary dressing immediately after a burn, after release of contractures and following scar revision. It has been used to achieve cover after the debridement of extensive infective processes involving the skin. Encouraged by these results we have assessed the application of Integra to augment and/or patch defects of the urinary bladder, diaphragm and the abdominal wall in the rat model. This was a pilot study and involved the incorporation of Integra in the diaphragm, the urinary bladder (extramucosal) and the muscle layer of the abdominal wall. Eight adult Wistar rats were given general anaesthesia and Integra was implanted with absorbable sutures at the sites mentioned. The omentum was hitched to the collagen matrix surface to revascularise the graft. The silicone was left in situ. The operative period was covered with antibiotics. The anaesthesia was then reversed. Postoperatively the rats were given analgesia and feeds started immediately. The rats were sacrificed after 3 weeks. The abdominal cavity was examined for adhesions. The Integra implant along with adjacent tissue was harvested and examined histologically. There were no visible intra-abdominal adhesions. The histology revealed good degree of neovascularisation and fibrosis in and adjacent to the implant. This was comparable to the changes seen in the skin. This pilot study has shown that implanting Integra invokes a similar response in deeper tissues and it can develop neovascularisation from the omentum. Hence, this could find some application in treating congenital conditions such as diaphragmatic hernias, abdominal wall defects and for bladders requiring augmentation. Our initial results are quite encouraging and we feel that this field should be further explored.

Setting standards for training and competence: the UK alcohol treatment trial.

AIMS: To examine factors that influence the recruitment and training of therapists and their achievement of competence to practise two psychological therapies for alcohol dependence, and the resources required to deliver this. METHODS: The protocol for the UK Alcohol Treatment Trial required trial therapists to be competent in one of the two trial treatments: Social Behaviour and Network Therapy (SBNT) or Motivational Enhancement Therapy (MET). Therapists were randomised to practise one or other type of therapy. To ensure standardisation and consistent delivery of treatment in the trial, the trial training centre trained and supervised all therapists. RESULTS: Of 76 therapists recruited and randomised, 72 commenced training and 52 achieved competence to practise in the trial. Length of prior experience did not predict completion of training. However, therapists with a university higher qualification, and medical practitioners compared to other professionals, were more likely to complete. The average number of clients needed to be treated before the trainee achieved competence was greater for MET than SBNT, and there was a longer duration of training for MET. CONCLUSIONS: Training therapists of differing professional backgrounds, randomised to provide a specific therapy type, is feasible. Supervision after initial training is important, and adds to the training costs.

Mechanisms by which area-based regeneration programmes might impact on community health: a case study of the new deal for communities initiative.

STUDY OBJECTIVE: To explore mechanisms by which area-based regeneration initiatives may impact on health. DESIGN: Case study of the New Deal for Communities programme, part of the UK National Strategy for Neighbourhood Renewal. MAIN RESULTS: Health impacts may result from three mechanisms: sociospatial stigma, community participation and the commissioning of projects designed to change the distribution of determinants of health, including access to services and healthy lifestyles. CONCLUSIONS: The present UK National Strategy for Neighbourhood Renewal includes improving health status as one of its key outcome measures. Area-based regeneration schemes such as the New Deal for Communities initiative should, intuitively, bring about health gain through their participatory approach to changing the physical and socio-economic environments. At present, however, the direction and magnitudes of these impacts are not clear.

Androgen and oestrogen receptor status of the human appendix testis.

Since the human appendix testis is a Mullerian duct derivative it has been theorised that rising oestrogen levels in puberty result in enlargement of this organ and consequent predisposition to torsion. This study sought to establish the presence or absence of both androgen and oestrogen receptors in the human appendix testis. Bilateral appendix testis specimens surgically excised from ten patients undergoing scrotal exploration for acute scrotum were stained immunohistochemically for androgen and oestrogen receptors. These were examined by light microscopy. The human appendix testis was found to express both oestrogen and androgen receptors. Marked regional variation of androgen and oestrogen receptor positivity was demonstrated. The surface epithelium and some stromal cells were androgen receptor positive, whereas oestrogen receptors were confined to ductular invaginations, gland-like structures and some stromal cells. Rising levels of androgens and oestrogens in pubertal boys may account for enlargement and the predisposition of the human appendix testis for torsion since this structure contains receptors for both.

A prospective comparison of tissue glue versus sutures for circumcision.

The safety of wound closure with tissue glue after surgery has been well established. The efficacy of its use in circumcision is poorly documented. The aim of this study was to carry out a comparative study of tissue glue versus suture closure after circumcision. The duration of the operative procedure, pain score, cosmesis and postoperative complications were evaluated. There were no complications in either group. There was no statistically significant difference in the pain score in both groups. However the mean time taken for tissue glue was 16.6 minutes and the mean time taken for sutures was 23.7 minutes. (p < 0.0001) which was statistically significant. The cosmetic appearance was found to be superior in the tissue glue group as there were no suture marks on the join of the shaft skin and foreskin base.

Rescue percutaneous coronary intervention immediately following coronary artery bypass grafting.

Perioperative graft failure after coronary artery bypass graft (CABG) can result in acute myocardial infarction with dire clinical consequences. We report a case of rescue percutaneous coronary intervention immediately after unsuccessful CABG. This approach salvaged the patient from cardiogenic shock and should be recognized as a viable alternative to immediate reoperation for certain patients.

Mechanisms for the development of esophageal atresia.

BACKGROUND: There is no universally accepted theory to explain esophageal embryology and the abnormal development that produces esophageal atresia. METHODS: The impact of Adriamycin administration on the pathogenesis of esophageal atresia was studied in the rat model of VATER association, from embryonic day (ED) 10 to ED 13. RESULTS: Tissues in the ED10 Adriamycin-exposed embryos displayed less cell proliferation as shown by the reduced population of MIB-5-labelled cells. Cell apoptosis that is characteristic of the normal ED 12 lateral epithelial folds of the foregut (the prospective site of tracheoesophageal septation) was absent in the foregut of the Adriamycin-exposed embryo. Histologic examination of the ED 11-exposed embryo showed the presence of abnormal notochord that was stretched, split, or tethered to the foregut. This contrasts with the normal embryo in which the notochord was localized in close vicinity of the ventral part of the neural tube and separated from the foregut by ample amount of mesenchyme. The abnormal localization of the notochord was accompanied by the lack of down-regulation of the sonic hedgehog (Shh) activity in the prospective site of future tracheoesophageal separation in the exposed ED 12 embryo. CONCLUSION: The authors proposed that the ectopic location of the notochord leads to the disruption in Shh signalling that may underpin the development of esophageal atresia.

Ways of coping and the health of relatives facing drug and alcohol problems in Mexico and England.

AIMS: To compare two contrasting socio-cultural groups in terms of parameters relating to the stress - coping - health model of alcohol, drugs and the family, and to test hypotheses derived from the model in each of the two groups separately. DESIGN: Cross-sectional, comparative and correlational, using standard questionnaire data, supplemented by qualitative interview data to illuminate the findings. PARTICIPANTS: One hundred close relatives, mainly partners or parents, from separate families in Mexico City, and 100 from South West England. Data sources. Coping Questionnaire (CQ), Family Environment Scale (FES), Symptom Rating Test (SRT), Semi-structured interview. FINDINGS: Mean symptom scores were high in both groups, and not significantly different. The hypothesis that relatives in Mexico City, a more collectivist culture, would show more tolerant - inactive coping was not supported, but there was support for the prediction that relatives in South West England would show more withdrawal coping. This result may be as much due to differences in poverty and social conditions as to differences in individualism - collectivism. As predicted by the stress - coping - health model, tolerant - inactive coping was correlated with symptoms, in both groups, after controlling for family conflict, but there was only limited support for a moderating role of coping. Wives of men with alcohol problems in Mexico City, and wives of men with other drug problems in South West England, reported particularly high levels of both engaged and tolerant - inactive coping. CONCLUSIONS: Tolerant - inactive coping may be bad for relatives' health: causality may be inferred but is not yet proved. Certain groups are more at risk of coping in this way. Qualitative data help understand the nature of tolerant - inactive coping and why it occurs despite the view of relatives themselves that it is counter-productive.

Addiction as excessive appetite.

The excessive appetite model of addiction is summarized. The paper begins by considering the forms of excessive appetite which a comprehensive model should account for: principally, excessive drinking, smoking, gambling, eating, sex and a diverse range of drugs including at least heroin, cocaine and cannabis. The model rests, therefore, upon a broader concept of what constitutes addiction than the traditional, more restricted, and arguably misleading definition. The core elements of the model include: very skewed consumption distribution curves; restraint, control or deterrence; positive incentive learning mechanisms which highlight varied forms of rapid emotional change as rewards, and wide cue conditioning; complex memory schemata; secondary, acquired emotional regulation cycles, of which 'chasing', 'the abstinence violation effect' and neuroadaptation are examples; and the consequences of conflict. These primary and secondary processes, occurring within diverse sociocultural contexts, are sufficient to account for the development of a strong attachment to an appetitive activity, such that self-control is diminished, and behaviour may appear to be disease-like. Giving up excess is a natural consequence of conflict arising from strong and troublesome appetite. There is much supportive evidence that change occurs outside expert treatment, and that when it occurs within treatment the change processes are more basic and universal than those espoused by fashionable expert theories.

Pathophysiology of atherosclerosis: development, regression, restenosis.

There is now a very large number of patients with coronary artery disease who have also undergone percutaneous interventions such as coronary angioplasty. Atherosclerosis and restenosis are two distinct pathologic processes with different underlying pathophysiologic mechanisms, different natural histories, different clinical presentations, and treatment strategies. Management strategies to target both processes are currently poorly applied in clinical practice. The development of integrated management strategies to target atherosclerosis, as well as restenosis in the postprocedural period remains a priority.

Treating ambulatory ischemia in coronary disease by manipulating the cell biology of atherosclerosis.

Obstructive coronary artery disease is the most common cause of morbidity and mortality in the developed world. Our understanding of the pathobiology of coronary atherosclerosis provides us with new opportunities to reduce myocardial ischemia by interventions that address these mechanisms directly. These interventions include lipid-lowering therapies that improve local coronary vasomotion, inflammation, and the procoagulant state. These interventions have also been shown to result in important reductions in clinical events, including angina pectoris, myocardial ischemia and infarction, and death. Ambulatory electrocardiography provides a versatile and quantifiable measure of regional myocardial ischemia. Reductions in ischemia, as quantified by this diagnostic modality, are associated with improved clinical outcomes that may reflect improvements in the cellular pathophysiology of coronary atherosclerosis. This review discusses new information regarding the interactions between low-density lipoprotein cholesterol, the cell biology of atherosclerosis, and the activity of ischemia in patients with coronary artery disease.

The comparative pathobiology of atherosclerosis and restenosis.

Percutaneous coronary interventions (PCIs) play an increasingly important role in the management of patients with coronary artery disease. However, these important procedures are complicated by restenosis in a sizeable number of patients. The pathobiology of atherosclerosis comprises a complex interaction among lipids, the endothelium, circulating and tissue inflammatory cells, platelets, and vascular smooth muscle cells. The superimposition of the mechanical and cellular consequences of PCIs on the abnormal substrate of atherosclerosis leads to a characteristic and distinct pathobiology that initiates and perpetuates restenosis. A clear understanding of the significant differences between atherosclerosis and restenosis will provide a rational basis for developing treatment plans that always address both problems. This article reviews and contrasts the pathobiology of atherosclerosis and restenosis and compares the mechanisms and time-course of these distinct entities.

Sphincter of Oddi dysfunction: two case reports and a review of the literature.

Sphincter of Oddi dysfunction is an underdiagnosed but important clinical condition. It should be considered in the differential diagnosis of biliary pain when the gallbladder sonogram shows no evidence of gallbladder disease. Hepatobiliary scanning (Tc-99m dimethyl iminodiacetic acid) may provide valuable information in the evaluation of these patients and may be helpful in monitoring response to treatment.
